Be it'known that 1, FRANK cin Bellman,-

",6 Yer hiwe invented certain new and ch t e following is aspecification.

v.ittfdevice -endj-gmqre particularly to the movable'meniberisprowithrenewable fusesI v the bje t imt n P 'W QZa -1- simple,compacftqandj efiicient device ation; Fi .1313 a longitudinal centralsee I "tiongand ig 4 is an end elevation of a'hinge 25 f-l je 'laas theform of a rectangular slab;. wi ntlfsunk holes 2 for the reception offor securing it in place upon o stilts} board. Near the oppositeends'ofithebase 1 are pairs of clips 3 with bindingposts 4 projectingtherefrom and secured to the base by screws 5 extending therethropghfrom the backside.

,The upper pair of clips 3. have transverse apertures for screws 6, andone member of each clip has a bearing collar 8 struck up therefrom intothe space between the members of the ilip to serve as a bcaringfor theswitch 1 blade section, and the aperture through the collar and the clipfromwhich it p is struckis screw threaded corresponding to t the threadon the screw 6. Between the head of the screw and the duter clip memberis a spring washer 7 which, when the screw is forced-'- -home, serves toyieldingly press the members of the clip into contact with the -""bladesection.

I The movable member of the switch comvrises twogpairs of blade sections9, 10 carried y fiansyerse bars 11 of insulating material.

The upper'pai-r 9 are transversely apertured width to form shoulders 12to engage the sidelinl'xprovements in Electric Switches, of

present "invention relates ,to electric s ch'the'fuses-are adaptedgtofheclamped in pps'itiol'l and of bar 1 1 and tongues 13 which extendtherethrough and are headed over on the inside of fuse receptacles 14;The lower pair of blade sections 10 are reduced in width at both ends toforin shoulders 15 and tongues 16. The lower ends of. the sections 10extend into gains out transversely in the lower bar 11 and the tongues16 extend therethrough and are .Patented Sept. 1, 1908.

headedover washers '17, and the tongues 16 of fuse receptacles 18. Thelength of the blade sections 1 0 is made sufficient to readily enten thelower contact clips 3 without interference of th latter with the bar 11or the fuse receptac' cs 18.

The fuse; rece tacles I L-and 18 are made 011 -shap'ed and ongitudinallyslotted to provi e s ringfin ers .19 for firmly contacting with t emetalic terminal caps 20 of the fuses 21 and the slots provide guides forthe heads of the pins 22'which secure the caps 20 to the fuse tubesand'thereby operate to position the. fuses so that their llldlQtltOI'S23 will .he'visible when the movable member of the switch is in closedposition.

"The lower bar 11 is provided with a handle 24 having a screw 25extending transversely through the bar and engaging a rectangular rod 26of insulating'm'aterial located on the inside of the bar at its centerand extending at right angles thereto and detachably engagin the upperbar 11 at its center. This detac able connection is formed by rovidingthe end of the rod 26 with a metal ic rod 27 which enters a hole 28inthe upper bar 11, and the latter has a thumb screw 29 extending from theunder side"and entering the hole 28. Both bars 11 are {joined for thereception of the ends of the rod 26 as indicatedin at'the upper ends ofthe sections extend through and are headed over the inner ends I I donot desn'e to restrict myself to the par-- ticular form or arrangementof pa'rts herein shown and described, since it is ap arent that they maybe changed and modifiemIwithout departing from my invention.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is,

1. In an electric switch, the combination of a pair of contact bladesections, fuse recep tacles secured .to the ad'acent ends of and inalinement with said lade sections, and means for silpportingsaid bladesections independent of said fuse receptacles.

2. In an electric switch, the combination of a pair ofcontact bladesections, cupshaped fuse receptacles secured to the adjacent ends of andin alinement with said blade sections, and means for supporting saidblade sections.

3. In an electric switch, the combination of a pair of contact bladesections, cupshapedfuse receptacles comprising a plurality of springfingers secured. to the adjacent ends of and in alinement with saidbladesections, and mea'ns'for supporting said blade sections. M"

4. In an electric switch, the combination of two insulating bars,contact blade sections secured to said bars, fuse receptacles secured tothe adjacent ends of and in alinement with.

' said blade sections, and means for supporting said bars in fixedrelative positions. 5. In an electric switch, the combination of twoinsulating bars, contact blade sections Lsecured to said bars, fusereceptacles secured to adjacent ends of said blade sections, and a rodrigidly connected to one of said bars and detachably connected to theother bar.

6. In an electric switch, the combination of a plurality of stationarycontacts, two insulating bars, contact blade sections secured to saidbars, fuse receptacles secured to adjacent ends of said blade sections,a rod rigidly secured to one of said bars and enterin an aperture in theother-bar, and a thum screw for engaging said rod extending into theaperture in the latter-bar from the under side thereof when the switchis in closed position.

7. A hinge clip for electric switches having a bearing collar struck upon the inside of one member, and an aperture in the other memberopposite said collar.

In witness whereof, I have hereunto set In hand this 29th day of July,1905. FRANK C. DE REAMER Witnesses:
